<P>PROBLEM TO BE SOLVED: To provide a wheel for automobile having a pneumatic pressure detection sensor that can easily and reliably change a battery. <P>SOLUTION: One of a plurality of decoration holes 6 formed in a disk part 3 is defined as a sensor fitting hole 10. The sensor fitting hole 10 is formed in a stepped hole consisting of a large diameter hole 11 and a small diameter hole 12 in this order from an outer surface side of the disk part 3. A pneumatic pressure detection sensor 20 includes a small diameter part 23 and a large diameter part 22 to be fitted to the small diameter hole 12 and the large diameter hole 11 of the sensor fitting hole 10, respectively, and a projecting piece part projected from an outer circumference of the large diameter part 22. The projecting piece part is fastened to and mounted on the disk part 3 by bolts while the small diameter part 23 and the large diameter part 22 are fitted to the small diameter hole 12 and the large diameter hole 11 of the sensor fitting hole 10, respectively, and the projecting piece part is brought into contact with the outer surface of the disk part 3, and connected to an air valve installed on a rim part 2 through a ventilation pipe. <P>COPYRIGHT: (C)2013,JPO&INPIT |
